SMALL-SIZE )BARREL ORGAN.

-- Application fi l ed July 30,1926 Serial No. 126,063, and in Germany November 14,1924.

This invention relates to a small size bar'- rel organ,, which can be transported and "played by any unskilled person by turning a handle. I

1 The novelty consists in that the sound box as'well'a'sthe'wind box are horizontally arranged so that: the sound box partly overor laps the wind box. This arrangement does not only permit of accommodating-the whole mechanism of the barrel organ in a small, oblong and low casing adapted to be carried onthehshoulder by a strap'but it permits also of simplifying the construction and of reducing the cost of manufacture.

.An .embodimentof the invention is shown, byz'way of example, in' the accompanying drawing'in which 1 Fig. 1 shows the improved toy-musical box in plan view. f a

Fig.v 2 is a side elevation of Fig-1.

Fig; 3 'is a verticalfsection through the Wind-box at the sideof theworm-wheel driving the blade-shaft.

Fig. 4 is a [verticalflsection through the '25 sound-box and through the rear fork-shaped bracket for the crank-shaft.

F ig. 5 shows the fork-shaped bracket in elevation viewed from the inner side in the shape priorto the fixing onthe' circular Fig. 6 is a section'on line EF of Fig. 4 showing.how-this'circular wall is closed by the foot of this fork-shaped bracket.

The wind-box is built-horizontally "into the sheet iron casing Z, is, '2', 3, 4 and the Vertical sound-box a, c is arranged under the perforated top-plate b of this sheet metal casing in such a manner thatits top plate at is situated in the same horizontal planelas the bottom-plate c of the wind-box the top plate and the bottom-plate being made of one piece of sheet-metal. In the wind-box (Z blades 2', fixed on avertical shaft 2, are adapted to rotate,a worm g] of wire being fixed by soldering on this shaft (Fig. 3). I With this worm y gears a wormwheel w, keyed on a crank-shaft it which is mounted in open slots g of plates 9 of a bearing bracket and securely held in the slots by a sheet-iron top-plate w fixed by flaps w on the plate g. The whole apparatus is securely fixed in the sheet-metalcasing by means of flaps f of the bottomplate a of the wind-box and by means of flaps h of the plate g.

'7 The edges a of the circular wall a are covered by a sheetrmetal-plate v, fixed by means of flaps e on this circular wall. A

' zinc-disc Z, having narrow slots Z rests upon a rib 9 on the inner surface of the wall a (Fig. {1), reeds m being fixed by'means of rivets m. under said slots Z. disc 1 rests acardboard-disc vo, which has radial slots at. (Fig. 2') wider than theslots l and than the reeds which fit almost accurately into the slots 1. 'A vertical pin 10 (Fig. l) traverses the discs 2' and 0 at the centre. On this pin 10 axworm wheel of thin sheet-metal is mounted which has catch claws r, formed by flaps, bent downward from the spokes s and resting on the cardboard-disc 0. A washer 12 on the pin 10 servesas abutment for a spiral-spring 12, wound around the pin and pressing upon the worm-wheel g so' that the flaps 1' are strongly pressed on the cardboard-disc, the head 14 on the lowerend 'ofpin lObeing ghereby strongly pulledkagainst the sound iscZ.

At the rotation of the worm-wheel the On the zinc- I cardboard-disc is also rotated and its slots n. uncover gradually the slots in the zincdisc so that-air can pass through the slots Z and make the reeds m vibrate, whenever at the rotation of the cardboard-disc its slots a come into register with the slots Z. The worm wheel g is slowly rotated by the worm p on the crankshaft u. For ensuring the correct engagementbetween the worm-wheel g and the Worm p the crank-shaft is mounted in front of and behind the worm in slots 14 of afork-shaped bracket t (Figs. 2, 4 and 5). The transverse bars 15 which connect the one with the other the arms of the fork t have extensions 16, gripping from above and below over tlierim of the wormwheel to guide the same accurately along the central line of the worm. This bracket is made in one piece with the cover-plate a.

The object to save space in accommodating the whole mechanism in a casing i, 3, is, 4, b which is similar to that of a barrel-organ is thus obtained with the simplest and cheapest means. This casing can be easily carried on the shoulder by a strap 7 to be attached to the upper edges of the end walls 3, 4 at 5, 6 so that the casing rests upon the left hip of the person .who carries it. To operate the barrel organ the casing can be shifted to the front of the body so that a crank to be intom plate of said sound box.

sertedat 8 (and which is not shown) can be turned.

v The improved barrel organ --can be used when the person who carries it 1s walking,

it can betransported in 'a travelling bag and it can be used alsoat home when placed ona table. 7 'Y 1. A small size barrel organ, comprising in combination with a casing, a wind box horizontally mountedm said casing, asound box developing a musical-scale horizontally horizontallymounted in said casing, a sound box developing amusical scale horizontally mounted in said casing partly on the top of said wind box, a sound disk in said sound box having sound slots, a cardboard dlsk on said sound disk and having slots for alternately covering and uncovering said sound slots, a toothed driving wheel for siowlyrotating'said cardboard disk, aslotted bracket embracing and guiding the rim of said drlvlng wheel, a driving crankshaft ournale din said slotted bearing, a worm, shaft inside said slotted on said crank bracket andlmeshing with said toothed drivingfwheel, a:.slit]ring"forming the wallvof said sound box, and a plate rigid with said slotted bracket and covering the edges of said slit ring to-close said=ring.

3. A-toy 'musical box, comprising in combination with a casing, a wind box horlzontally omounted in saidcasing, a sound box: horizontally mounted in said casing-partly on tl1etop of said wind box, a sound disk in said sound box having sound slots, a cardboarddiskon said sound. disk-and having slots for alternately covering and uncovermg said sound slots, a toothed driving wheel for slowlyro'tatlng said cardboard dlsk, a
